Obviously if you are close enough for the GP to be on your plotting sheet you can draw a circle of position.
I’m sure that many years ago I saw an example of this in a book. It was a fix from just one body, the Sun, passing close overhead, and it was called a ‘zenith fix’. However, today I can find no mention of it either on-line or in any of my books including Lecky, where I was sure I must have seen it. Am I dreaming again? DaveP
